Which statement best describes mosquito flight distances across species?

• A. Flight distance is constant across species
• B. Flight distance varies by species
• C. Only males fly short distances
• D. All species fly many miles

Answer: (B)

Mosquitoes don’t all travel the same distance; how far they fly depends on the species and its ecology. Some species stay close to their breeding sites and human dwellings, often only hundreds of meters from where they developed as larvae. Others are capable of longer-range dispersal, sometimes covering kilometers, especially when seeking hosts or new breeding sites. This variation reflects differences in feeding habits, habitat preferences, and flight capability across species. That’s why the statement that flight distance varies by species is the best description. It’s not constant across species, it isn’t limited to males, and not every species flies many miles.
